COUPLING.

Specification of Letters Patent.

Patented Nov. 1L5, 1921.

Application filed October 12, 1918. Serial No. 257,856.

To all whom it may concern:

Be it known that I, l/VILLIAM J. DRUCKER, a citizen of the United States, and a resident of VVoodhaven, in the county of Queens and State of New York, have invented a Coupling, of which the following is a full, clear, and eXact description.

My invention relates to mixing devices, particularly suitable for mixing mayonnaise. It forms an improvement over my Patent No. 1,240,688, issued September 18, 1917, and from which it characterized by the means for supporting the stationary beater.

An object of the invention is to provide a simple, inexpensive and durable coupling for connecting the stationary beater to a stu'iport.

in the accompanying drawings forming a par; of the application, similar characters of reference refer to corresponding numbers in all the figures, of which- Figure l is an elevation of the mixer embodying my invention, the rotating platform and the lower part of the receptacle being in section to illustrate details of construction i 2 is avertical section on the line 3 8 i 1;

Fig. 3 is a horizontal section on the line -i-i Fig. 1.

Referring to the drawings, 7 is the base which carries the motor 8 and the transmission, not illustrated, which couples the motor to the platform 9 supported by the base '7. The platform 9 has an annular groove in proximity to its margin, which groove is bridged at suitable intervals by lugs 11, preferably forming an integral part of the platform.

A receptacle has its bottom 13 raised so that the wall of the receptacle descends below the bottom to enter the recess 10, the portion of the wall below the bottom having notches M for engaging the lugs 11 on the platform and whereby the receptacle is secured to the platform and therefore when motion is imparted to the platform by the motor the receptacle is caused to rotate with the platform. The number and location of the lugs and notches make is easy for any operator, however unskilled, to properly place the receptacle for operation. The bottom 13 of the receptacle 12 has a central socket 15 to engage a centering stud 16 rising from the platform and whereby the receptacle is prevented from movement in the groove 10 of the platform if there should be any play.

The base 7 has ears from which columns 18 rise, and the columns 18 support a frame 19 above the base which forms a support for a container 20 from which oil or vinegar may be discharged into the receptacle 12 when the same is on the platform. The support 19 has a depending lug 21 to which the stationary stirrer 22 may be secured by a pin 23. The lug 21 is to one side of the axis so as to maintain the stirrer in a central plane when the same is secured to the lug 21.

To prevent the swinging of the stirrer on the pin 23 dowel pins 24: are provided on the lug 21 for engaging suitable recesses in the frame of the stirrer 22. The pin 23 preferably has a milled head 25 extending out beyond the support 19 so that the same can be easily manipulated. The bottom 26 of the stirrer 22 is raised in the central part, as shown at 27, to prevent the sticky materials such as eggs, from lodging between the bottom of the receptacle and the bottom of the stirrer.

I claim:

The combination of a stationary support having a depending member provided with a horizontal threaded aperture and with pins projecting from one face thereof, a rigid member to be supported from the depending member of the support, provided with an opening registering with the opening of the depending member and with recesses at the sides of the opening and into which extend the pins of the said depending member, and a headed pin having one end screw threaded provided with a flange intermediate of its length, said pin passing loosely through the opening of the member to be supported with its flange resting against said member and screwed into the opening of the depending member.
